To all whom it may concern.-

Be it. known that I, EUGENIO K. HAYES, residing at Kewanee, in thecounty of Henry and State of Illinois, and a citizen of the UnitedStates, have invented a new and useful Improvement in Force-Pumps, ofwhich the following is a full description, reference being had to the,accompanying drawings, in which Figure is a front elevation, Fig. 2 aside elevation, Fig. 3 an enlarged sectional elevation, of the cylindersand piston and receiving-chamber, Wit-h the lifting-rods and the tubebroken oil? and partly in section; Fig. 4, atop view of thereceiving-chamber; Fig. 5, a bottom view of the receiving-chamber; Fig.6, a detail, being a side elevation of one of the cylinders partlybroken out and the cap-plate removed; Fig. 7, a bottom view of one ofthe cylinders with the cap-plate removed; Fig. 8, a bottom view of oneof the cylinders with the cap-plate in position; Figs. 9 and 10, a topview and a side elevation, respectively, of the walking-beam; Fig. 11, adetail of the handle; Fig. 12, a detail of the cap or fulcrum on whichthe walking-beam is mounted Fig. 13, a detail of the upper end of themain pipe; Fig. 14, a plan View of the stand; Figs. 15 and 16, a sideelevation and a top view,'respectively, of the guide for the piston-rod;Fig. 17, a detail of the upper end of the piston-rod for the attachmentof a windmill-rod;'Figs. 18, 19, and 20, details of the clamp connectingthe piston-rod with the windmill-rod; Figs. 21 and 22,'side elevationsshowing a support for the discharge-pipe; Figs. 23 and 24, a sideelevation and a top View of a walking-beam into which the handle isslipped.

The objects of this invention are to construct a force-pump, which canbe made double-acting or single-acting, as may be desired, and which canbe used with one cylinder operated from a handle and the other from awindmill or other motive power, and to improve generally theconstruction and operation of force-pumps; and its nature consists inthe several parts and combinations of parts hereinafter described, andpointed out in the claim as new.

In the drawings, A represents the cylinders, each formed of an annularwall having at the lower end a chamber A, the bottom of which isperforated with a number of holes a, and in contact with the bottomplate on the inside is a screen a for preventing the entrance of sandand other sediment into the chamber and cylinder. The upper wall of thechamber A is provided with an opening ct, leading into the cylinder A,and this opening is controlled, as shown, by aweighted flap-valve a".The upper end of the cylinder A is encompassed by a cap ','through whichis an opening for the passage of the piston-rod.

B is the piston-rod, having a longitudinal hole its entire length, andthe lower end of this tube or rod carries a piston B, formed,

as shown, of a packing b, inclosed between a rim or flange b on the tubeB, and a nut screw-threaded onto the end of the tube.

C is a brass packing-ring,into which the upper ends of the tube orpiston-rod B are screwed, and this ring 0 is screw-threaded into thereceiving-chamber, the end 0 of the ring forming the seat for a weightedfiapvalve 0. Two cylinders and pistons are used, each similar to theother in its construction, and, as shown, the weighted flap-valves C forthe tubes or piston-rods B; are both attached to the same piece offlexible'material O, which material is secured to the bottom of thereceiving-chamber by a boltc and a washer c, as shown in Fig. 3.

D is the receiving-chamber of an elongated rectangular shape, having inthe bottom two openings to receive the packing-rings C of the respectivetubes B, and allow the water to pass from the tubes alternately into thechamber, making a continuous supply, and this chamber on its top plateis provided with a boss d, with a central screw-threaded opening leadinginto the chamber. The chamber D is of sufficient length to locate thecylinders side by side Without interference with the working of each,and its width is nearly the same as the diameter of the cylinder.

E is the tube leading from the supply-chamber D to the discharge-spoutand extending up beyond the point of attachment of the discharge-pipe toform an air-chamber. This tube can be made up of sections of pipesecured together by suitable couplings, and its length will depend uponthe depth of the well or other reservoir with which the pump is to beused.

F is the discharge-pipe attached at its lower end to a coupling E on thetube E, and having a discharge-nozzle F.

G is a base-plate, through the center of which the tube E passes, andhaving at one side a boss or annular projection f, with a circularopening for the passage of the discharge pipe F, and, as shown, thedischarge-pipe is locked by a set-bolt f, and, if desired, set-' boltscan be screwed into the collar at the center of G for locking the tubeE.

II represents the rods for reciprocating the cylinders A, a rod beingused for each cylinder, and each rod having at its lower end a fork II,the arms h of which pass through ears g, one on each side of the cap A",and ears g, one on each side of the chamber A, and 011 the rods h of thefork II are secured collars h, to abut against the top of the plate orcap A, and the lower end of each rod h is screw-threaded to receive anut h, by means of which the chamber A and the cap or plate A can bedrawn snugly against the ends of the cylinder A, forming a closeconnection around the ends of the cylinder. The fork ll furnishes aconnection with the rods h, and also the means for securing the heads tothe cylinder, and this fork presents an effectual obstacle against theunscrewing of the parts by which the cylinder-heads might becomeloosened when the rods H are attached to their operating walking-beam orhandle.

I is a guide-block attached to the tube E and projecting outward on eachside in line with the rod H, and having at each end a hole for thepassage of the rod, so that the rod will not bend or buckle in use.

J is a walking-beam mounted 011 the upper end of the tube E. Thiswalking-beam has a longitudinal slot J to receive the end of a supportJ" on the end of the tube E, and to which support the walking-beam ispivotally connected by a suitable pin or bolt 1', and, as shown, one endonly of this walking-beam is provided with a socket for the reception ofa handle; but both ends could be socketed, if so desired. One rod I'Isteps or terminates at its connection with the walking-beam end, theconnection being, as shown, by means of a pin or pivot j passing throughthe end of the beam and the rod 11. The other rod His flattened at itsupper end and made to pass above the walking-beam for the purpose ofattaching the pitman operated by a windmill or other motive power, andthis rod H has its end connected to the walking-beam by a bolt j, whichcan be removed to disconnect the rod from the walking-imam and leave itfree to be worked by the pitman. The rods H are further guided andmaintained in a direct vertical line by slots 6, formed in the stand orsupport G.

K is a handle secured to the end of the walking-beam J, the end of thehandle entering the socket it of the walking-beam.

L is a clasp provided with cars 1, through which and the upper end ofthe projecting rod H a bolt or pin can be passed to attach the clasp tothe rod, and to this clasp is bolted or otherwise secured the end of thepitman operated from a windmill or other power. (Not shown.)

In use, when the pump is operated by handpower, the operator, bytakinghold of the handle K, reciprocates the cylinders A through therods II, one cylinder rising as the othcris falling, and such movementsof the cylinders form a double-acting force-pump by which the water islifted into the chamber 1), thence passing into the tube E and outthrough the discharge-pipe F. The downward movement of each cylinder Aforces water through the openings (and screen, when used) into thechamber A, and thence into the cylinder A through the valve a", which isthrown up, the valve 0 at the top of the pipe of the descending cylinderbeing thrown down. At the same time water is discharged into the chamberD through the other cylinder which is being lifted, the valve a" of suchcylinder being closed and the valve 0' open, and, as shown, the openingof the valve 0' is stopped or limited by projections (1' depending fromthe top of the chamber D 5 and this filling of the one cylinder anddischarging of the other will occur at each up-and-down stroke of thehandle K, making the discharge a continuous one.

The pump can be used as a single-acting pump, by disengaging the rod H,having the flat end, so that the movement of the handle K andwalking-beam J will operate but the one rod, producing a filling anddischarging of a single cylinder; and both cylinders can be operatedindependently by disconnecting the rod H with theflat end from thewalking-beam and connecting it to a windmill-pitman or other motivepower, leaving one cylinder to be operated by the handle and beam andthe other by the pitman, thus enabling the pump to be used as anattachment to a windmill or other motive power, and at the same time tobe operated by hand independently, so that in case the mechanical deviceoperating one rod becomes useless the pump can still be 01% eratedthrough the other rod by hand.

The employment of the cylinder to do the lifting, instead of the plungeror piston, i11- creases the simplicity and power of the pump,

in that no packing-box is required around smaller cylinders to be usedfor the samelift, and by having the cylinders operated throughdetachable rods two single-acting pumps are had, each workingindependent of the other. The location of the rods which reciprocate thecylinder outside of the pipe through which the water passes leaves theentire inside measurement of the pipe free and clear for the passage ofthe water, thereby enabling an inch pipe to be used with a greatercapacity than a much larger pipe, in which the plunger would be used.The rods which operate the cylinders also through the fork at the lowerend serve to hold the heads of the cylinders to the body, and when theserods are secured at their upper ends to the walking-beam it will be seenthat no turning can be had to loosen the holding-nuts and disconnect therods from the cylinders or unfasten the cylinders themselves; and thecylinders being located in the bottom of the well or other reservoir arealways submerged, so that the pump is kept primed, all of which featuresmake the pump very reliable and effectual in use.

The pump shown in Figs. 21 and- 22 is of the same general constructionas that already described, except that a support G is provided runningfrom a socket on the stand G to a band G, which band clasps or encirclesboth the tube E and the tube F, and the object of this bracing,furnished by the rod G'- and band G, is to hold the tubes againstvibration in use.

The walking-beam shown in Figs. 9 and 10 is formed of a single piecehaving a longitudinal slot J and a screw-threaded socket is to receivethe screw-threaded end of the handle K. This walking-beam could be madein two pieces, as shown in Figs. 22 and 23, the pieces being held apartby interposed pieces to form the slot J, and instead of the handle Kbeing screwed into the walking-beam it can he slipped into the socket isand held therein by tightening-bolts 76', which bolts also at one endserve to connect the two parts of the walking-beam J together, the otherend of such walking-beam being connected by a minates at its attachmentwith the handle,

the handle can be reversed and connected with the other rod, and stillhave a singleacting pump operated from the handle, and the breakage ofthe rod to which the windmill is attached can be remedied by reversingthe handle and connecting the other rod with the pitman and it will beseen that a doubleacting force-pump with reciprocating cylinders bothworking at the same time is had, and also a single-acting force-pump,either cylinder being capable of working independently of the other,either by hand or from a windmill or other motive power; or one cylindercan be worked by hand and the other by windmill or other motive powerindependently, producing the effect of a double-acting force-pump thecylinders of which are operated by independently-acting power.

The rods H each have a connecting-nut m,

l by which the attachment to the walking-beam can be readily changed.

What I claim as new, and desire to secure by Letters Patent, is-

The combination of the cylinders A A, the

tubes B B, provided with pistons B B within said cylinders, thevalve-controlled receiving chamber D, the tube E, extending upwardlyfrom said chamber, the beam J, fulcrumed in a support on the upper endof said tube, and the detachable rods H, one of which is 6X- tendedabove the beam for connection with a wind-wheel, whereby the pump may bemade either double-acting or single-acting and the opposite sides beoperated either bythe same power or one by hand and the other bywindwheel, substantially as described.
